The heit l, is supported on carrier rollers which are made up oil elements illustrated in Figures 4 and 5. A east spider comprising a hub portion, lel, with radiating arms, l5, is first bored out approximately at the e251" of its hub. Through the bore, lli, there then inserted a careiiully' centered mandrel which is mounted on centers in a grinding' machine, whereupon the erds' ofthe radial arms, l5, are ground od juist enough to make the spider a tight drive tt for .pipe or tub-V ing, 17, which .is to serve as; the'rim-,oi 'tire of the roller. The spider is then forced or driven longitudinally into a 'section of'this tubing, 17, to the desired position, as indie" cated in Figure 5; owing toV the elasticity of the tubular wall, 17, it may thus be stretched into an approximately polygonal' form as indicated by the dotted line in Figure 5, but on account of the multiplicity of the radial arms, l5, the nal form ot' the roller-Willbe nearly enough cylindrical to serve ,all practical purposes.' Figure 2 shows rollers, of this type mounted onthe con-regler frame. At its oppositeends the cross-member, 8, 'supports two brackets, 18, in which are secured the ends of a bent tubular axle, 19 for the rollers, the bends, 20, of said axle being: lodged vin upwardly-open Cradle brackets. 2.1, also carried on the member, 8. is formed ot standard pipe, and to v.t'ueilitate its asseinbly it is made in two sections joined by e coupling, 2Q, so that before the two sections are coupled together, the middle roller, F, and one of the end rollers, G, can be entered on the longer section ot the axle from opposite ends thereof. While the other roller, G, canibe slid onto the shortll axle section from its outer end. The two "sections are then secured together by. the coupling 22, and lodged in the cradle bracket, 2l, whereupon the end lfnrackets. 18, may be engaged with the end portions of the axle, l5), and the elbowsx applied thereto with their grease Cups, E24. as shown in Figure '2. Small apertures. 25, in the tubular axle, 19, are posi tione'l to register with the huh portions, lll, ot the spiders in tbe.rollers, F and G, 'for feeding to the hearing surfaces the lubricant supplied through grease oups, 24.' This construction permits a. large supply of lubricant and 5, of the next sec` :Preferably as indiceted portions, 9,9, or the ber, *26, may be slightly -tor is indica-ted et J'v in Figure msdos?,

to be carried in the hollow journul or axle, 19, thus minimizing trouble from inadtxpiaie lubrication.

To enabletlie belt, l, to hold n loud ol materiel, particularly, bulk material, eren when operating at a relatively steep incline, it is provided with flights, 26, Whit-.hareshown as bars of 1liet stock 'extending cross- Wise ot' the belt through the middle portion ofv its width but not to its extreme edges, each bar, 26, being supported by en angle member, 2?,.Whose. width trensverselyot' the belt is inu'eh less than that of the bei' itself, so that the seenrelnent of its foot portion, 28,' to the belt Will not-seriously interfere with the troughing' thereof which is efleoted 'br the inclined rollers, G,'shown in igure i?. in Figure 7, the end bent with respect to the middle portion which isseeured to the supporting Atingle, such bending being in the direction oi travel of the belt, l, and thus tendin to center the load of bulk material on the be t and prevent spillage from the edges of the belt. lVithin the box-lile l eonveyer "frame-`r thei'e are mounted' the obliquely-disposed boards, 80,'

are arranged toeeoonnno'dete the flight bars, 26, .between them,v and to prevent undue draggingof the bars upon these rails, the extreme lateral portions of the belt beyond thev end'or the bars, 26, are supported upon obliquely-disposed rollers, H, which are substantially similar in Construction to the rolls, G, which serve for troughing the upper ply of the belt, '1.' However, there being no middle roller corresponding to the upper rollers, F. the rolls, H, are shown as support-ed each` upon an individual axle carried in a bracket. 32, lodged upon the crossmelnber, 9, of the traine. i
